BACKGROUND/OBJECTIVES: The objectives were to investigate the effect of a 12-wk intervention with behavioral modificationon clinical characteristics and dietary intakes of young and otherwise healthy obese and to identify factors for successful weightloss. The goal was to lose 0.5 kg per week by reducing 300-500 kcal/day and by increasing physical activities. SUBJECTS AND METHODS: Forty four obese subjects (BMI > 25) and 19 normal weight subjects (BMI 18.5-23) finished the 12-weekintervention. Obese subjects participated in 5 group educations and 6 individual counseling sessions. Normal weight subjectsattended 6 individual counseling sessions for evaluations of dietary intake and exercise pattern. Anthropometric and clinicalcharacteristics and 3-day dietary records were evaluated at baseline and week12. RESULTS: Weight and serum triglyceride and free fatty acid concentrations in obese group decreased significantly with intervention. Intakes of energy, fat, and cholesterol decreased significantly in the obese. Active participation, realistic weight loss goal setting,and weight gain after high school graduation not during childhood were identified as key factors for successful weight loss. CONCLUSIONS: The 12-week intervention with behavioral modification resulted in reduced energy and fat intakes and ledto significant weight loss and improvements of clinical characteristics in the obese. The finding that those who became obeseduring childhood lost less weight indicates the importance of ‘early’ intervention.
